SU910698A1 - Dispersed 1,4-diarylamino anthraquinone blend dyestaff for polyester fiber - Google Patents

Description

  “. - l.

This invention relates to dispersed dyes, namely, to a new blend dispersed 1, -darylamino-anthraquinone dye, useful for dyeing polyester fibers.

The mixed dispersed 1 L-diarylamino anthraquinone dye is known, consisting of 1, -dianilido-1, A-DI-P-toluidino and 1-an-Lido-P-toluidium-anthraquinone. The dye dyes the fiber in blue-green color: GP. The known dye is obtained by quinizarin condensation with an equimolar amount of aniline and p-toluidine and dispersing with usual additives for 25 hours to emit the dye outlet form with a dispersion of 7-8.V

A disadvantage of the known dispersed dye is the insufficient degree of dispersion of J-B / i. In addition, the well-known dye has low resistance to welding, sublimation and light.

The purpose of the invention is to obtain a new mixed dye of turquoise color with a high dispersion,

resistant to light, sublimation and welding. .

The goal is achieved by applying a new mixed disperse dye containing (in aa.%) Compounds of the formulas:

The paste from the filtration stage is stirred in 500 ml of a 1-2% aqueous solution of sodium hydroxide at BS-C 3, filtered, washed water to neutrality. 36.8 g (from theory) of a dye base are obtained.

According to chromatographic analysis, the resulting dye base is assumed to be a mixture containing wt.%:. .
